[RFC PATCH] wifi: rt2x00: use VCO_IC 0x2 for RF3053 on 2.4 GHz

[Ho Jie Feng <hjf3108@gmail.com>]

Using the 0x1, the VCO calibration result is 0x7f on channels 6
and below. Using 0x2 fixes it.

Hardware: Netgear WNDA4100 (USB 0846:9013, RT3593 rev 0402, RF3053)

RFC for this since I am not sure if it is a generic fix, since the
vendor driver also doesn't use VCO_IC=0x2.
Is this also a known issue?

Testing on different hardware would be appreciated.
